Keywords: quantum geometry; localizability; Planck Scale
Summary/Abstract: I will discuss some aspects of the concept of “point” in quantum gravity, using mainly the tool of noncommutative geometry. I will argue that at Planck’s distances the very concept of point may lose its meaning. I will then show how, using the spectral action and a high momenta expansion, the connections between points, as probed by boson propagators, vanish. This discussion follows closely (Kurkov, Lizzi and Vassilevich, 2014).
